So first convert 2 3/4 to improper fraction
2 3/4=8/4+3/4=11/4
11/4a=19 1/4
convert 19 1/4 to improper
19 1/4=76/4+1/4=77/4
11/4a=77/4
multiply both sdie sby 4
11a=77
divide by 11
a=7
Answer:
a
Step-by-step explanation:
g(x)=-x²
f(x)=|x+2|
f(3)=|3+2|=5
(g*f)(3)=g(f(3))=g(5)=-5²=-25
Answer:
3052.1 in³
Step-by-step explanation:
The volume of a sphere is given by the formula ...
V = 4/3πr³ . . . . r is the radius
The radius is half the diameter, so is 9 in. Then the volume is ...
V = (4/3)(3.14)(9 in)³ = 972(3.14) in³ ≈ 3052.1 in³
